Imagine a futuristic scenario where artificial intelligence (AI) can reconstruct missing or incomplete data with remarkable precision, akin to automatically restoring the missing audio track from a silent movie by analyzing its images. This is precisely the promise behind Diag2Diag, a cutting-edge AI developed by a collaborative team led by Azarakhsh Jalalvand at Princeton University. Published recently in Nature Communications, Diag2Diag represents a significant breakthrough in fusion plasma diagnostics by translating data from one type of sensor into a synthetic, high-fidelity version of another. This approach yields data that not only aligns with real-world measurements but also surpasses the resolution capabilities of traditional sensors. Such advancement holds the potential to revolutionize plasma monitoring in fusion reactors, enhancing control while minimizing complexity and costs.

Fusion plasma, the searingly hot, ionized gas that fuels fusion reactions, is notoriously difficult to measure with precision. Tokamaks, doughnut-shaped devices designed for plasma confinement, rely on an array of diagnostic tools to monitor parameters like temperature and density, enabling scientists to maintain plasma stability. Among these diagnostics, Thomson scattering stands out by measuring electron temperature and density, but it is limited in temporal resolution and spatial coverage, especially at the plasma’s edge, known as the pedestal. The edge is the most critical region for plasma stability, where rapid fluctuations can significantly impact performance. Diag2Diag’s AI offers a transformative capability by synthetically enhancing these diagnostics, effectively providing super-resolution data from existing, often sparse and limited, sensor outputs.

What makes Diag2Diag exceptionally compelling is its foundational concept: using data from multiple sensor modalities to infer comprehensive and detailed information that no single sensor can achieve independently. By correlating data from several diagnostic tools operating simultaneously, the AI constructs a nuanced, synthetic dataset for diagnostics that may be slower or physically constrained in spatial coverage. This capacity to synthesize high-fidelity diagnostic data from complementary inputs means that future tokamak designs could rely less on extensive arrays of physical sensors, resulting in streamlined, more compact reactors that retain or even improve diagnostic accuracy.

The implications for fusion energy are profound. The transition from experimental devices to commercial-grade fusion reactors demands machines capable of continuous, reliable operation without interruption. Present-day experimental fusion devices can afford downtime caused by failing sensors; however, commercial plants must maintain stability 24/7 to be viable energy sources. Diag2Diag addresses this challenge by ensuring redundancy and robustness in plasma diagnostics, reconstructing accurate data in real time, even when some physical sensors degrade or malfunction. This AI-based resilience is a critical step toward practical fusion reactors that can reliably deliver clean, limitless power.

Underlying the success of Diag2Diag is an international collaboration, pooling expertise and experimental data across institutions such as Princeton University, the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), Chung-Ang University, Columbia University, and Seoul National University. The training data for the AI stems from measurements at the DIII-D National Fusion Facility, a premier U.S. Department of Energy user facility dedicated to fusion research. This collaborative framework ensured that Diag2Diag’s synthetic data generation models were thoroughly grounded in real experimental conditions, enabling widespread applicability and robust performance.

The name “Diag2Diag” reflects its fundamental purpose: it takes input from one diagnostic system and synthesizes the expected measurements of another, essentially translating one set of diagnostic observations into another domain with enhanced detail. This approach is particularly valuable because the different diagnostics vary drastically in temporal and spatial resolutions. For example, while Thomson scattering can measure electron temperatures and densities swiftly, it cannot fully capture rapidly evolving plasma instabilities occurring at the pedestal. Diag2Diag fills this gap by enhancing the effective resolution of existing diagnostics—essentially giving plasma physicists a sharper and more continuous window into the plasma’s dynamic edge behavior.

One particularly critical application of Diag2Diag concerns the study and mitigation of edge-localized modes (ELMs), intense bursts of energy capable of damaging a tokamak’s inner walls. These disruptive events have been a persistent hurdle for the fusion community. The novel AI has provided deeper insight into how resonant magnetic perturbations (RMPs)—small, deliberate modifications of magnetic fields—can be used to control or suppress ELMs. By generating detailed synthetic diagnostic data, Diag2Diag supports the theory that RMPs create “magnetic islands” at the plasma edge, flattening temperature and density profiles in that region, thereby stabilizing the plasma. This insight not only advances theoretical understanding but also guides practical strategies for ELM control.

The ability of Diag2Diag to unravel the complex interplay between plasma parameters at previously inaccessible temporal and spatial scales represents a paradigm shift in fusion plasma research. It elevates AI from a supplementary computational tool to an integral part of the diagnostic and control toolkit. Importantly, this AI-driven diagnostic enhancement reduces reliance on costly hardware, simplifying reactor design. According to Egemen Kolemen, the principal investigator jointly appointed at PPPL and Princeton University, Diag2Diag effectively delivers “diagnostic boosts” without additional physical sensors, which has major implications for making future fusion reactors more compact, economical, and reliable.

PPPL researchers emphasize that the evolution of fusion technology requires innovations not only in physical engineering but also in data science and control systems. The integration of AI approaches like Diag2Diag into fusion research exemplifies this shift. By enabling real-time, detailed monitoring of plasma conditions, this technology maximizes operational safety and efficiency. It also paves the way for fewer diagnostic systems, reducing maintenance burdens and the potential for errors—a critical advance as fusion reactors move towards commercialization and scale-up.

Moreover, the broader scientific impact of Diag2Diag extends beyond fusion. The AI’s ability to recover, reconstruct, and super-resolve missing or degraded diagnostic data points to applications in complex systems beyond plasma physics. Fields such as aerospace, spacecraft diagnostics, and robotic surgery, where sensor robustness and reliability are paramount, stand to benefit from this technology. The AI bridges the gap when sensors fail or provide sparse measurements, ensuring continuity and safety in mission-critical environments.

Further research is already underway to expand Diag2Diag’s capabilities. The research team indicates strong community interest in adapting the AI framework to a wider range of fusion diagnostics and perhaps entirely different fields. This development trajectory promises a future where AI not only complements but enhances scientific instrumentation across diverse applications, unlocking previously inaccessible insights derived from otherwise limited or incomplete datasets.

The research underpinning Diag2Diag was generously supported by the U.S. Department of Energy through multiple awards, the National Research Foundation of Korea, and the Princeton Laboratory for Artificial Intelligence. Such funding reflects a growing recognition of the essential interplay between advanced data science and physical science to address grand challenges such as sustainable energy. In a world racing toward decarbonization and energy independence, innovations like Diag2Diag underscore AI’s potential as both a scientific enabler and a practical solution provider.

Ultimately, Diag2Diag exemplifies how blending AI with advanced plasma physics can produce revolutionary tools essential for making fusion power a reality. By enabling high-fidelity plasma diagnostics with fewer sensors and enhanced robustness, the technology accelerates the journey toward economical, compact fusion energy devices that can operate reliably at scale. As fusion researchers continue to decode plasma’s mysteries, AI-driven enhancements in diagnostics and control will be crucial pillars supporting the dawn of a new era in energy production.
